OVFTool Import Multiple VMs into vApp or Template

Hi There,

Please can someone advise if it is possible, I would like to import multiple VMs into the same vApp or Template in vCloud.

When testing i get this error...

Opening vCloud target: vcloud://export@derenvvcd.mgsops.net:443/cloud
Error: vApp name already found in the catalog. Either overwrite it or choose a different name.
Completed with errors

Thanks in advanced,
